摘　　要：联合仿真法预估疲劳寿命包括获取载荷历程、应力应变场和材料参量三个方面内容。文章在此基础上依据企业提供的二维图纸,在三维造型软件Pro/Engineer中建立某型号变速器的第一齿轮轴实体模型。根据有限元基本理论,建立该轴的有限元模型。最后在有限元分析系统MSC.Nastran中进行该轴的应力分析,得出应力应变。采用Pro/E和ADAMS/V iew的专用接口模块Mechanism/Pro实现两者之间的数据转换,最后仿真得出齿轮轴与从动齿轮的载荷曲线,其与理论计算值十分接近。有限元分析及动力仿真结果对进行齿轮轴的疲劳寿命预估提供了必须的数据,为进一步来预测服役齿轮轴的剩余寿命有着重要的作用。Co-simulation method to estimate the fatigue life contains three aspects：accesing the load curve,stress-strain field and material parameters.This paper is based on the two-dimensional drawings supplied by enterprise,create a solid model of the primacy gear shaft and the meshing driven gear by using three-dimensional modeling software Pro/Engineer.According to the basic theory of finite element,the finite element model of the gear shaft is established.Finally,we carry out stress analysis of the gear shaft and obtain the data of stress and strain.By using Mechanism/Pro which is the dedicated interface module of Pro/E and ADAMS/View,the data transfer is achieved between the two.The load curve of gear shaft and driven gear shaft obtained by simulation is very close with the calculated value.The result of finite element analysis and dynamic simulation provide necessary data for estimating the fatigue life of the gear shaft.It plays an important role in predicting the remaining service life of the gear shaft for further.
